  Purpose

The whitening action of an investigative hydrogen peroxide/sodium fluoride containing mouth rinse will be evaluated through stain removal using mean Lobene Stain Index over 14 days compared to a currently marketed hydrogen peroxide containing whitening mouth rinse (Crest® 3D White Multi-Care Whitening Rinse, Glamorous White, Fresh Mint). A currently marketed toothpaste (Colgate® Cavity Protection) will be included as the negative control in order to compare to brushing alone.

225 healthy volunteers will be enrolled in this two week study. Volunteers who qualify to be in this study will have an equal chance of being assigned to one of the three treatment groups. Volunteers will have a total of 5 clinic visits including 1) screening, 2) baseline 3) Day 4 (after 3 days of use), Day 8(after 8 days of use) and Day 15 (after 14 days of use). Volunteers will maintain a diary at home to record each treatment use. Examinations for oral hard/soft tissue assessment and extrinsic tooth stain after the subject brushes with water and floss will be completed at Baseline and repeated at Clinic Visits 3, 4, and 5, which are on Days 4, 8 and 15 post baseline (i.e., after 3, 7, and 14 days of product use).

Primary Outcome Measures:
  • Lobene Stain Index Composite Scores at Day 15 [ Time Frame: Day 15 (after 14 Days of Product Use) ] [ Designated as safety issue: Yes ]

    Tooth stain surface and stain intensity will be assessed by using scores on the Lobene Stain Index (two part visual scale), scored 0 - 3. Where 0 = no stain, 1 = light stain, 2 = moderate stain and 3 = heavy stain. The second part of the scale will examine the surface of the tooth on a scale of 0-3, where 0= no stain, 1 = covering up to 1/3 of the region, 2 = covering > 1/3 to 2/3 of the region and 3 = covering > 2/3 of the region.

    The mean composite score will be determined by multiplying the individual tooth stain surface and stain intensity scores and summing then dividing by the number of regions scored for the subject (or tooth).



Secondary Outcome Measures:
  • Lobene Stain Index Composite Scores at Day 4 [ Time Frame: Day 4 (after 3 Days of Product Use) ] [ Designated as safety issue: Yes ]

    Tooth stain surface and stain intensity will be assessed by using scores on the Lobene Stain Index (two part visual scale), scored 0 - 3. Where 0 = no stain, 1 = light stain, 2 = moderate stain and 3 = heavy stain. The second part of the scale will examine the surface of the tooth on a scale of 0-3, where 0= no stain, 1 = covering up to 1/3 of the region, 2 = covering > 1/3 to 2/3 of the region and 3 = covering > 2/3 of the region.

    The mean composite score will be determined by multiplying the individual tooth stain surface and stain intensity scores and summing then dividing by the number of regions scored for the subject (or tooth).


  • Lobene Stain Index Composite Scores at Day 8 [ Time Frame: Day 8 (after 7 Days of Product Use) ] [ Designated as safety issue: Yes ]

    Tooth stain surface and stain intensity will be assessed by using scores on the Lobene Stain Index (two part visual scale), scored 0 - 3. Where 0 = no stain, 1 = light stain, 2 = moderate stain and 3 = heavy stain. The second part of the scale will examine the surface of the tooth on a scale of 0-3, where 0= no stain, 1 = covering up to 1/3 of the region, 2 = covering > 1/3 to 2/3 of the region and 3 = covering > 2/3 of the region.

    The mean composite score will be determined by multiplying the individual tooth stain surface and stain intensity scores and summing then dividing by the number of regions scored for the subject (or tooth).


  • Lobene Stain Index Area Scores at Day 4 [ Time Frame: Day 4 ] [ Designated as safety issue: Yes ]
    Tooth stain surface will be assessed by using scores on the Lobene Stain Index scored 0 - 3. Where 0= no stain, 1 = covering up to 1/3 of the region, 2 = covering > 1/3 to 2/3 of the region and 3 = covering > 2/3 of the region.

  • Lobene Stain Index Area Scores at Day 8 [ Time Frame: Day 8 ] [ Designated as safety issue: Yes ]
    Tooth stain surface will be assessed by using scores on the Lobene Stain Index, scored 0 - 3. Where 0= no stain, 1 = covering up to 1/3 of the region, 2 = covering > 1/3 to 2/3 of the region and 3 = covering > 2/3 of the region.

  • Lobene Stain Index Area Scores at Day 15 [ Time Frame: Day 15 ] [ Designated as safety issue: Yes ]
    Tooth stain surface will be assessed by using scores on the Lobene Stain Index, scored 0 - 3. Where 0= no stain, 1 = covering up to 1/3 of the region, 2 = covering > 1/3 to 2/3 of the region and 3 = covering > 2/3 of the region.

  • Lobene Stain Index Intensity Scores at Day 4 [ Time Frame: Day 4 ] [ Designated as safety issue: Yes ]
    Tooth stain intensity will be assessed by using scores on the Lobene Stain Index visual scale, scored 0 - 3. Where 0 = no stain, 1 = light stain, 2 = moderate stain and 3 = heavy stain.

  • Lobene Stain Index Intensity Scores at Day 8 [ Time Frame: Day 8 ] [ Designated as safety issue: Yes ]
    Tooth stain intensity will be assessed by using scores on the Lobene Stain Index visual scale, scored 0 - 3. Where 0 = no stain, 1 = light stain, 2 = moderate stain and 3 = heavy stain.

  • Lobene Stain Index Intensity Scores at Day 15 [ Time Frame: Day 15 ] [ Designated as safety issue: Yes ]
    Tooth stain intensity will be assessed by using scores on the Lobene Stain Index visual scale, scored 0 - 3. Where 0 = no stain, 1 = light stain, 2 = moderate stain and 3 = heavy stain.

Detailed Description:

Approximately 225 generally healthy subjects that meet the required inclusion/exclusion criteria will be enrolled in this 2 week, examiner-blind, single center, randomized, controlled, parallel-group clinical trial to ensure that approximately 215 subjects complete the study. At baseline, the prescreened subjects will present to the clinical site for baseline examinations (oral tissue assessment, extrinsic tooth stain assessment). Subjects will brush with water, then floss, have an oral exam and tooth stain assessment. Subjects will be randomly assigned to one of three groups using a randomized code provided by the sponsor:

  • Negative Control - Brushing twice daily with an ADA - Accepted fluoride-containing dentifrice (Colgate® Cavity Protection).
  • Brushing twice daily with an ADA - Accepted fluoride-containing dentifrice (Colgate® Cavity Protection) followed by rinsing twice daily with 10 ml for 60 seconds with an investigative peroxide and fluoride containing mouth rinse
  • Brushing twice daily with an ADA - Accepted fluoride-containing dentifrice (Colgate® Cavity Protection) followed by rinsing twice daily with 15 ml for 60 seconds with Crest® 3D White Multi-Care Whitening Rinse, Glamorous White, Fresh Mint

Immediately after randomization, subjects will begin use of their assigned test treatment. The site staff will supervise the first rinse treatment, and rinse treatments occurring on examination days. The negative control group will not have supervised brushing at the clinic to avoid the possibility of changing their usual brushing habits. All home use will be unsupervised and following label instructions. Subjects will be required to maintain a diary card to document twice-daily product use by recording their assigned oral care routine. For Clinic Visit 3, 4, and 5, subjects will be instructed to not use the treatment rinse in the morning prior to their clinic visit, because that treatment rinse will be supervised during their clinic visit. Subjects may brush as normal in the morning prior to these clinic visits.

During the study, subjects will follow their usual interdental cleaning (e.g. flossing) and dietary habits. Subjects will not be allowed to use any other unassigned oral care products (mouth rinse, dentifrice, or other tooth whitening products), or have their teeth professionally polished, bleached, or whitened by a dentist or hygienist.

Examinations for oral hard/soft tissue assessment and extrinsic tooth stain after the subject brushes with water and floss will be repeated at Clinic Visits 3, 4, and 5, which are on Days 4, 8 and 15 post baseline (i.e., after 3, 7, and 14 days of product use). Compliance will be evaluated at Visits 3, 4, and 5 by weighing residual volumes of returned mouth rinses and by reviewing the subject diary. Subjects will receive the ADA-Accepted fluoride containing dentifrice and a soft bristled toothbrush at their baseline visit.

During the course of the study, subjects may use an interdental cleaning device to remove impacted food between the teeth and may continue using an interdental cleaning device regularly if it is part of their usual oral care regimen.
